Product description
SEN-Color from Joy-It is a color sensor based on the TCS3200 chip. The sensor uses an array of 64 photodiodes with red, green, blue, and clear filters to measure the color components of incident light and convert them into a frequency signal. The output is a square wave whose frequency corresponds to the light intensity. Using the control pins S0–S3, both the photodiode type and frequency scaling can be selected, allowing flexible adjustment to various lighting conditions and measurement accuracy. The sensor can be operated with both Arduino and Raspberry Pi, and Joy-It provides ready-to-use code examples for both platforms.
In testing with an Arduino Uno, communication was stable, and the sensor produced clear and reproducible results after calibration. The calibration procedure requires measuring minimum values without a target and maximum values against pure color surfaces, which is best done using Joy-It’s included RGB test sheet. Results showed that the sensor quickly identifies primary colors and can be used for basic color detection in robotics or measurement applications. One drawback is that the sensor is sensitive to ambient light and therefore requires some shielding to ensure stable readings. Overall, the SEN-Color is an affordable and educationally useful color sensor for teaching and prototyping.
The module is equipped with four white LEDs that illuminate the object during measurement to improve color detection accuracy. The sensor is compatible with Arduino, Raspberry Pi, and Micro:bit.
